摘要
Abstract
The mechanism of prior particle boundary ( PPB) and its effects on microstructures and mechanical properties in powder metallurgy GH4169 are discussed, meanwhile the measures on minimizing PPB precipitation has been analyzed. The result indicate that MC carbide is the major constituent of previous particle boundary, and the powder metallurgy GH4169 shows better property with powder pre-heat treatment.关键词
