Dieses Buch befasst sich mit der Herstellung von Verbundwerkstoffen mittels Pulvermetallurgie. Es beinhaltet auch den H rtetest zur Bestimmung der mechanischen Eigenschaften und die Bearbeitung zur Optimierung der MRR. Mit Hilfe von SEM, EDS und H rtetest wurden Mikrostruktur und Eigenschaften untersucht, um den Einfluss von Sintertemperatur und -zeit auf die Verbundwerkstoffe zu ermitteln. Die mikroskopischen Aufnahmen von Cu-Graphit zeigen die saubere Grenzfl che und die gute Kompatibilit t zwischen Matrix und Verst rkung. Das Ergebnis zeigt, dass der Cu-SiC-Verbundwerkstoff nach dem Sintern eine gleichm igere Struktur aufweist, die berall dort zu finden ist, wo sich das Verst rkungsmaterial im Grundmaterial befindet. Die Bearbeitung des hergestellten Cu-SiC-Verbundwerkstoffs ist im Vergleich zu anderen Werkstoffen einfacher, da er eine h here Materialabtragsrate (MRR) aufweist. Die Ergebnisse dieser Untersuchung werden f r verschiedene Fertigungsindustrien und Forscher, die auf diesem Gebiet arbeiten, von Nutzen sein.

Ce livre se concentre sur la fabrication de mat riaux composites par la m tallurgie des poudres. Il inclut galement le test de duret pour d terminer les propri t s m caniques et les op rations d'usinage pour obtenir un MRR optimal. A l'aide du SEM, de l'EDS et du test de duret , la micro structure et les propri t s ont t tudi es pour conna tre l'effet de la temp rature et du temps de frittage des mat riaux composites. Les micrographies de Cu-graphite refl tent l'interface propre et la bonne compatibilit entre la matrice et le renforcement. Le r sultat montre que le composite Cu-SiC a une structure plus uniforme visualis e apr s le frittage, partout o le mat riau de renforcement est situ dans le mat riau de base. L'usinage du composite Cu-SiC fabriqu est plus facile que les autres car il a un meilleur taux d'enl vement de mati re (MRR). Les r sultats obtenus par cette recherche seront utiles pour diverses industries manufacturi res et les chercheurs travaillant dans ce domaine.

Este livro est focado no fabrico de material composto com metalurgia do p . Inclui tamb m o teste de dureza para encontrar as propriedades mec nicas e a opera o de maquina o para obter a optimiza o do MRR. Com a ajuda de SEM, EDS e teste de dureza foram investigadas a micro estrutura e propriedades para conhecer o efeito da sinteriza o de materiais compostos de temperatura e tempo. Os micrografos de Cu-graphite reflectem a interface limpa e a boa compatibilidade entre matriz e refor o. O resultado mostrou que o composto Cu- SiC est a ter uma estrutura mais uniforme visualizada ap s a sinteriza o, em todo o lado material de refor o localizado no material de base. A maquinagem de Cu-SiC composto fabricado mais f cil de comparar do que outras porque tem mais taxa de remo o de material (MRR). Os resultados obtidos por esta investiga o ser o teis para v rias ind strias transformadoras e investigadores que trabalham neste campo.

Questo libro incentrato sulla fabbricazione di materiali compositi con la metallurgia delle polveri. Include anche la prova di durezza per individuare le propriet meccaniche e le operazioni di lavorazione per ottenere un MRR ottimale. Con l'aiuto di SEM, EDS e test di durezza sono state studiate la struttura e le propriet dei materiali compositi per conoscere l'effetto della temperatura e del tempo di sinterizzazione. Le micrografie di Cu-grafite riflettono l'interfaccia pulita e la buona compatibilit tra matrice e rinforzo. I risultati hanno mostrato che il composito Cu-SiC ha una struttura pi uniforme visualizzata dopo la sinterizzazione, ovunque il materiale di rinforzo si trovi nel materiale di base. La lavorazione del composito Cu-SiC fabbricato pi facile rispetto agli altri perch ha un tasso di rimozione del materiale (MRR) pi elevato. I risultati ottenuti da questa ricerca saranno utili a varie industrie manifatturiere e ai ricercatori che lavorano in questo campo.

This book is focused on fabrication of composite material with powder metallurgy. It also includes the hardness test for finding the mechanical properties & machining operation for getting optimize MRR. With the help of SEM, EDS and hardness test Micro structure and properties were investigated to know effect of sintering temperature and time composite materials. The micrographs of Cu-graphite reflect the clean interface and good compatibility between matrix and reinforcement. The result showed that Cu- SiC composite is having more uniform structure visualized after the sintering, everywhere reinforcement material located in base material. Machining of fabricated composite Cu-SiC is more easy compare than other because it is having more material removal rate (MRR). The results obtained by this research will be useful for various Manufacturing Industries and researchers working in this field.

This book gives you the skills you need to use Python for penetration testing, with the help of detailed code examples. This book has been updated for Python 3.6.3 and Kali Linux 2018.1. Key FeaturesDetect and avoid various attack types that put the privacy of a system at riskLeverage Python to build efficient code and eventually build a robust environmentLearn about securing wireless applications and information gathering on a web serverBook DescriptionThis book gives you the skills you need to use Python for penetration testing (pentesting), with the help of detailed code examples. We start by exploring the basics of networking with Python and then proceed to network hacking. Then, you will delve into exploring Python libraries to perform various types of pentesting and ethical hacking techniques. Next, we delve into hacking the application layer, where we start by gathering information from a website. We then move on to concepts related to website hacking—such as parameter tampering, DDoS, XSS, and SQL injection. By reading this book, you will learn different techniques and methodologies that will familiarize you with Python pentesting techniques, how to protect yourself, and how to create automated programs to find the admin console, SQL injection, and XSS attacks. What you will learnThe basics of network pentesting including network scanning and sniffingWireless, wired attacks, and building traps for attack and torrent detectionWeb server footprinting and web application attacks, including the XSS and SQL injection attackWireless frames and how to obtain information such as SSID, BSSID, and the channel number from a wireless frame using a Python scriptThe importance of web server signatures, email gathering, and why knowing the server signature is the first step in hackingWho this book is forIf you are a Python programmer, a security researcher, or an ethical hacker and are interested in penetration testing with the help of Python, then this book is for you. Even if you are new to the field of ethical hacking, this book can help you find the vulnerabilities in your system so that you are ready to tackle any kind of attack or intrusion.
