中文摘要：

一块热渗出镍铝铜牌的微观结构和性质上的热处理的效果被调查。试验性的材料是通过不同过程对待的热，包括熄灭，使正常化，变老并且退火，并且他们的微观结构，腐蚀抵抗和机械性质被描绘。它被发现那熄灭所有阶段转变了成“然而，使原因阶段正常化转变了成的阶段”的原因，并且分阶段执行。当熄灭的样品是年老的时，好阶段从同样熄灭的微观结构被猛抛“阶段。退火引起转变“进并且阶段。测试看那熄灭，使正常化并且变老的机械性质的结果改进试验性的材料的张力的力量和坚硬，与在延伸的相应下降。退火提起延伸，但是减少张力的力量和坚硬。而且，镍铝铜的腐蚀抵抗评价从对更坏在下列顺序更好：，熄灭，使正常化，热渗出并且退火。与腐蚀测试增加的暴露时间，然而，在那些镍铝铜牌之间的平均腐蚀率的差别变得小。

英文摘要：

The effect of heat treatment on the microstructure and properties of a hot-extruded nickel-aluminum bronze was investigated. Experimental materials were heat treated through different processes, including quenching, normalizing, aging and annealing, and their microstructure, corrosion resistance and mechanical properties were characterized. It is found that quenching causes all β phase transformed into β phase, however, normalizing causes β phase transformed into β α and κ phases. When the quenched sample is aged, fine phase is precipitated from the as-quenched microstructure of β＇ phase. Annealing causes the transformation of β into a and κ phases. The results of mechanical property tests show that quenching, normalizing and aging improve the tensile strength and hardness of the experimental material, with a corresponding fall in elongation. Annealing raises the elongation but reduces the tensile strength and hardness. Furthermore, corrosion resistance of nickel-aluminum bronze ranks from worse to better in the following order： aged, quenched, normalized, hot-extruded and annealed. However, with the exposure time of corrosion test increasing, the difference of average corrosion rate between those nickel-aluminum bronzes tums small.
