Powder Metallurgy Data. Refractory, Hard and Intermetallic Materials · 1 Introduction

Abstract

This chapter presents an introduction to Powder Metallurgy (PM) Data and its focus on formed and consolidated products from powder along with the properties of these products. Although there is no clear borderline between functional and structural materials, it is generally understood that the chemical or physical properties of functional materials are of higher importance for the application than geometry or mechanical strength, even if the application affords shape and mechanical coherence. Raw materials and many processing details usually affect decisively the property profile of a PM product. For this reason the rapid prototyping methods based on metallic powders, functionally graded materials and nanomaterials were excluded, and so were metallic foams and materials consolidated by self propagating high temperature synthesis. Many PM materials cannot be manufactured any other way except PM, e.g. high melting temperature metals, hard metals, immiscible alloys as used for electrical contacts and brake linings, or several hard magnetic materials, high temperature superconductors and nano-grained materials. PM structural parts found their niche between cast and machined parts, because in general they offer better mechanical properties and geometrical reproducibility than castings and have more favorable productivity than machined components.
