The results showed that with increasing of FeS content,both the density and conductivity of composite were reduced,the hardness was increased and the microstructures were homogenized.When FeS content was less than 15% and more than 10%,the hardness of composite was conformably in this section.
FeS颗粒弥散强化Cu基复合材料是一类具有优异性能的新型功能材料，它具有高强度、高耐磨性、抗高温软化能力优良等综合物理性能和力学性能，同时兼顾了Cu的传导性，这与FeS的性能特征紧密相关。

At present,the rate laws and reaction mechanisms of pyrite oxidation,pyrite and chalcopyrite formation,uraninite and magnetite dissolution in aqueous solutions are mainly studied,and it is discovered that (1)oxidation rate of pyrite controlled by surface reaction assume fractional dependence on Fe3+ and O2 molalities in acid solutions;(2)Pyrite cannot nucleate directly from solutions below 300 ℃,it can only form initially through sulfidation of a FeS precursor. The rate equation of reaction between FeS and H2S to form pyrite is of the second order;(3)Chalcopyrite is formed by reactions of pyrrhotite or pyrite with Cu2+,the former proceeds via a series of mediate metastable phases of Cu-Fe sulfide,whereas the rate equation of the latter is apparently of the first order which is controlled by surface reaction;(4)The nonlinear behavior of magnetite dissolution at acid pH can be represented by a shrinking core model coupling with surface reaction and diffusion transport.
目前主要研究了水溶液中黄铁矿氧化、黄铁矿和黄铜矿形成、晶质铀矿和磁铁矿溶解的速率定律和反应机理，发现：(1)酸性溶液中黄铁矿的氧化速率对Fe3+和O2浓度呈分数依赖并受表面反应的控制；(2)低于300 ℃时黄铁矿不能从溶液中直接成核，而需初始地通过FeS先驱物的硫化生成，FeS与H2S反应形成黄铁矿的速率方程为二级；(3)磁黄铁矿或黄铁矿与Cu2+反应均可形成黄铜矿，前者经历了一系列准稳的Cu-Fe硫化物的中间物，后者的速率方程为表观一级并受表面反应的控制；(4)酸性pH时磁铁矿的非线性溶解行为可采用表面反应扩散输运耦合的收缩核模型来描述。

weldability：焊接性
如果钢材中硫含量太高,则会形成FeS,FeS是低熔点夹杂物,当钢材温度高於985℃时,此低熔点夹杂物先熔融而形成晶粒间液态薄膜,以致造成热脆性(Hot Shortness). (3) 随著含硫量增加,钢材的焊接性(weldability)会随著下降.
