摘要
研究了尺寸对1C17Ni2热处理后力学性能的影响结果,认为铁素体的量、尺寸及碳化物析出是导致其韧性恶化的原因。对比了520℃和330℃两种回火温度对性能的影响,确定了适合锻件热处理的回火温度,适当地延长回火时间,有利于提高韧性。
Effect of size on mechanical properties of stainless steel 1Crl7Ni2 forging after heat treatment was studied. It showed that the quantity, size of ferrite and carbide precipitates deteriorated the toughness. By comparison of the effeects of tempering at 520℃ and tempering at 330℃ on the properties, the appropriate tempering temperature was specified. It is helpful to improve the toughness by elongating of tempering time properly.
