Abstract

It is shown that initial treatment (quenching or annealing) has a significant effect on the evolution of the structure of hafnium bronze upon dynamic channel-angular pressing (DCAP). Upon annealing, hafnium becomes bound into particles of the intermetallic compound Cu₅Hf, and the annealed samples are only insignificantly strengthened upon DCAP. Upon quenching, Hf remains in the solid solution, and the strengthening effect upon DCAP is much greater. Twinning becomes the main deformation mechanism for quenched bronze upon DCAP.

初压对the压青铜组织的影响

摘要

结果表明，初始处理（淬火或退火）对动态通道角压制（DCAP）时ha青铜结构的演变具有显着影响。退火后，ha结合到金属间化合物Cu ₅ Hf的颗粒中，退火后的样品仅在DCAP上得到了微不足道的强化。淬火后，Hf保留在固溶体中，对DCAP的强化作用要大得多。孪晶成为DCAP淬火青铜的主要变形机制。
