摘要：
Mechanically milled AISI316L stainless steel, commercially pure Titanium and Ti-6Al-4V alloy powders are sintered by Hot Roll Sintering (HRS) process. Microstructure of materials produced by HRS process consists of a Shell & Core Hybrid Microstructure, that is, a shell structure with nano grains and a core structure with work-hardened coarse grains. All of the HRS materials demonstrate not only superior strength but also enough elongation. The mechanical properties are strongly influenced by the shell/core microstructure. The Shell & Core nano-meso hybrid microstructure by HRS process has been proved to be very effective to improve mechanical properties.
