  martensite phase
A martensite phase is formed in the surface layer of both blasted and scraped specimens.
      
This greater resistance to localized corrosion can be attributed to an increased stability of the natural passive film resulting from a higher concentration of chromium atoms in solution for the martensite phase.
      
The observed decrease in full width at half maximum (FWHM) in the ferrite- martensite phase was presumed to be due to the dynamic recovery effect that was likely to occur within the material close to the crack tip as a consequence of fatigue cycling.
      
The residual stress and volume fraction of strain-induced α'- martensite phase in 304L SS was varied with the rolling conditions.
      
The X-ray diffraction (XRD) technique was employed to study textures and residual stress development in the stainless steels due to cold working and to quantify the volume fraction of α'-martensite phase formed in the metastable SS.

In this paper the cold rolling strengthening and the straininduced martensite phase transformation of Fe-Mn and Fe-Mn-Al alloys have been studied. Quantitative measurements of the phase volumes and the mechanical properties of these alloys after cold rolling have been done. Experimental data show that, in the Fe-Mn alloys containing 15-30% Mn, increasing the content of Mn can retard α-martensite transformation. Further increasing the content of Al can retard the ε-martensite transformation,...

In this paper the cold rolling strengthening and the straininduced martensite phase transformation of Fe-Mn and Fe-Mn-Al alloys have been studied. Quantitative measurements of the phase volumes and the mechanical properties of these alloys after cold rolling have been done. Experimental data show that, in the Fe-Mn alloys containing 15-30% Mn, increasing the content of Mn can retard α-martensite transformation. Further increasing the content of Al can retard the ε-martensite transformation, so that at a certain chemical composition of the alloys, an Fe-Mn-Al alloy with stable austensite siructure during cold rolling can be obtained.

A dual-phase steel 15Mn2Nb was developed by using Mn as a primary alloying element to strengthen the ferrite and improve the hardenability of the steel and Nb as an additional element to refine the microstructure. Changes in microstructure and properties during intercritical quenching and deformation at these temperatures have been studied in comparison with steel 15. Experimental results show that after prequenching and then intecritical quenching in the α+γ region a "pearlite-like" dual-phase structure can be achieved with alternately arranged fine needles of the ferrite and martensite phases. After intercritical deformation followed by direct quenching a "fibrous" dual-phase structrue was observed in which the ferrite and martensite phases are unidirectional oriented in forms of fine fibers and the ferrite fibers are made up by very fine(<1μm) equiaxed grains connected to each other. The two structures mentioned above can appreciably improve the strength of the steel with the maintenance of high ductility and are considered as effective methods for developing high strength and high ductility of ferrite-martensitic dual-phase steels.

The specimens of 18—8 type stainless steels with different contents of C andN were deformed by tension of rolling at various temperature(77k,293k and373k),and hydrogen was electrolyticaly charged to some specimens.The internalfriction has been measured by transverse vibration and torsion pendulum methods.x-ray diffraction technique have been used to check phase of specimens.The results obtained are summarized as follws:1.The 325K internal friction peak(500Hz)originates in deformd austenite.2.Clear distinctions among the 325k-peak and other peaks,such as hydrogen-peak at 300k(500,Hz)and cold work peak at 335k(1Hz)for same type steelhave been drawn.3.A peak at 360k(500Hz)due to stain induced α'-martensite has beenfound.4.The peak temperatur changes from 325k fo 360k with increasing amountof martensite phase in specimens which cotain both austenite and α'-martesitephases.

本文对18—8型奥氏体不锈钢的各种变形条件下的塑性变形试件,电解渗氢试件的内耗进行了实验研究,用X 射线结构分析及薄膜试件透射电子显微镜分析方法,分析了上述试件的位错结构及塑变诱发马氏体相变。主要得到了以下结果:1.此钢冷范性变形后在振动频率500H_z 左右于325°K 所出现的内耗峰是由形变奥氏体引起的,与形变诱发马氏体无关;2.已将上述内耗峰与固溶氢内耗峰,振动频率为1H_z 左右时出现的335°K 内耗峰进行了严格的区别;3.此钢的形变诱发马氏体在振动频率为500H_z 左右时,于360°K 出现另一个内耗峰;4.在一定范性变形条件下出现奥氏体和马氏体两相混合组织时,在325°K 和360°K 范围内(~500H_z)所出现的内耗峰是形变奥氏体内耗峰与形变诱发马氏体内耗峰相叠加而形成的。
