The deformability of brass L63 under equal-channel angular pressing (ECAP) after a preliminary heat treatment (annealing at 600°C or quenching from different temperatures) is studied. The ECAP is conducted at room and elevated temperatures. It is shown that ECAP of brass L63 is possible only at elevated temperatures after preliminary annealing.

ECAP法初步热处理对黄铜变形的影响

研究了黄铜 L63 在经过初步热处理（600°C 退火或不同温度淬火）后等通道角挤压 (ECAP) 下的变形能力。ECAP 在室温和高温下进行。结果表明，黄铜 L63 的 ECAP 只能在初步退火后在升高的温度下进行。
