Impact tests have been carried out on nodular cast iron in -the cast and forged conditions from -85℃ to 1070℃. The results indicate that nodular cast iron of predominantly ferritic matrix possesses two brittle temperature ranges (below 20℃ and between 550 and 700℃), and one comparatively more ductile range (between 850℃ and 1050℃).

The process of decomposition of supersaturated tetragonal martensite during the first stage of tempering is investigated by considering the characteristics of motion of a carbon atom from one interstitial position to another within the martensite matrix. It is evident that not all the carbon atoms take part simultaneously in the process of precipitation, some remain in solution for a longer time, others shorter, some mobile, others stationary. By assuming that each transition from one state of motion to...

The process of decomposition of supersaturated tetragonal martensite during the first stage of tempering is investigated by considering the characteristics of motion of a carbon atom from one interstitial position to another within the martensite matrix. It is evident that not all the carbon atoms take part simultaneously in the process of precipitation, some remain in solution for a longer time, others shorter, some mobile, others stationary. By assuming that each transition from one state of motion to another has a definite probability, which is independant of time and carbon concentration but dependant on temperature and the nature of crystalline matrix, it can be shown that an isothermal decomposition curve can be expressed as a series with exponential terms, the coefficients of which are related to the distribution of carbon atoms in different states of motion. The agreement between this expression and the existing experimental data is satisfactory. The general tendancy of the variation of the coefficients with temperature is just what should be expected.

本文是作者从马氏体回火第一阶段中的等温分解曲线来研究分解过程。这种等温曲线最初接近时间的一次方的指数关系,越后则越不到一次方关系的分解时率。作者认为这种曲线反映了分解过程瞬变的本质和晶格间隙中碳原子运动迟留的特徵。假定了间隙碳原子从任一种运动情态转变到另一种情态都有一定的几率以后,等温分解曲线可以被表示成为一系列的时间的指数函数的和。每一指数项中时间的系数和运动情态转变的几率有关。这种几率和碳原子的浓度及时间无关,它们是温度的函数且和晶体间架的性质有关。指数项的系数则和碳原子在各种运动情态中的分布有关。这样的方式可以把实验数据代表到如所需要的精确度,而凭着所得的系数可以对推测分解过程的机构有所帮助。

The structural changes in certain quenched ferritic, austenitic and duplex stainless steels during subsequent reheating are described and discussed in detail.In 16-6 Cr-Mo stainless steel, austenite formed at certain solution treatment temperature is metastable and decomposes during subsequent reheating. New ferrite α′ forms at the γ/α interphase boundaries, the rejected carbon atoms then diffuse into the matrix forming alloyed carbides surrounding the γ/α phase boundarries.Fine carbides precipitated from ferrite in 16-6 Cr-Mo, 16-2.5-6 Cr-Ni-Mo, and 16-5-6 Cr-Ni-Mo steels in the early stages of ageing are metastable, during prolonged heating they redissolve and are gradually replaced by χ-phase. Some residual carbides serve as the nuclei of the growing χ-phase. The structure of quenched 16-15-6 Cr-Ni-Mo steel is austenitic, during subsequent heating only M_6C and M_(23)C_6 mixed carbides are precipitated.Both the alloyed carbides and χ-phase may markedly affect the hardness of the steels studied. In the duplex steels χ-phase is a good strengthener, manifesting pronounced hardening effect at elevated temperature.

本文叙述并讨论了几种固溶处理过的高钼不锈钢在不同温度时效过程中,组织结构变化的情况.16-6Cr-Mo不锈钢在800-1000℃保温,δ-铁素体首先在原来的γ/α相界上形成,然后或者由奥氏体晶粒四周向着中心,或者由晶粒一端向着另外一端推进,最后奥氏体将退缩到晶粒中心或者一个晶粒隅上消失.在600-700℃保温,则发现有层片状铁素体在奥氏体晶粒内形成,然后逐渐增多长大,最后全部代替了奥氏体.在16-6Cr-Mo、16-2.5-6及16-5-6Cr-Ni-Mo不锈钢中,从铁素体内沉淀出来的细小碳化物是一种过渡组织,在x相的成核与长大过程中,它们将不断地进行溶解.16-15-6 Cr-Ni-Mo不锈钢属奥氏体型,在不同温度进行固溶处理,奥氏体都很稳定,在随后的恒温处理过程中,只有碳化物从奥氏体内析出.在这几种钢中碳化物及x相的析出,均能显著地改变钢的硬度.在所研究的两种复相不锈钢中,都观察到有由于x相析出所引起的沉淀硬化现象.
