Abstract: Hydroturbine blades in hydroelectric power plants are subjected to erosion. Currently these blades are made of 13/4 martensitic stainless steel (ASTM grade A743). This steel suffers from several maintenance and welding related problems. Nitronic steels are being considered as an alternative to martensitic stainless steels since they have good weldability. In present work, erosive behaviour of 13/4 Martensitic and Nitrogen alloyed austenitic stainless steel (23/8N steel) has been studied. Cavitation erosion tests were carried out in distilled water at 20 KHz frequency at constant ampl

The tensile fracture of two austenitic stainless steels with different degrees of stability for low temperature strain induced martensitic transformation was investigated. A stable AISI type 310 stainless steel displayed typical tensile stress-strain curves with decreasing work hardening rate at temperatures in the interval of 25 to-196°C, in which no martensitic transformation occurred. By contrast, a metastable type 302 stainless steel with martensitic transformation from 25 to-196°C showed a range of plastic deformation with increasing work hardening rate.

By XRD, TEM, martensitic volume fraction measurement, etc., the results show that the strain-induced martensitic transformations of the two different components were different significantly.

In this respect, many attempts have been made to modify the surfaces of austenitic stainless steels to increase their surface hardness and wear resistance without scarifying the corrosion resistance [2-6].

Abstract:

The role of martensitic phase transitions in the embrittlement of stainless steels by hydrogen has been one of persistent controversial theme studied during recent years. The unresolved question, concerns the role of hydrogen in hydrogen induced phase transformation of the γ(fcc) austenite to α‘(bcc) and ɛ (hcp) martensite phases in the fracture mechanisms. The purpose of this study is to report the results of a TEM analysis of martensitic phase transitions under conditions of high hydrogen fugacities such as cathodic polarization in the absence of any externally applied stress.The results dem

Abstract:

13%-Cr martensitic stainless steels are widely used in the production of many mechanical components that require high hardness and good corrosion resistance. In the present work, 20mm-diameter 13Cr-2Ni-2Mo steel bars were quenched by induction heating (IH) method and after that tempered in a farness. 240 hours corrosion test of the bars was carried out using a salt spray testing method (JIS Z 2371:2000). The results were compared to two stainless steels, SUS304 and SUS440C. Their inner hardness distributions were measured. It was found that the hardness of IH-quenched and farness-tempered 13Cr

Abstract Martensitic stainless steels are suitable for diverse structural applications but degrade when subjected to wear-prone activities in service. To enhance their service life, the densification of high Cr, martensitic, X190CrVMo20-4-1 tool steel powder on two different martensitic stainless steel substrates via supersolidus liquid-phase sinter (SLPS) cladding was investigated. The objective was to assess the influence of the difference in compositions of the martensitic stainless steels employed as substrates on the interfacial diffusion, microstructure, hardness and bonding strength of

Abstract:

The microstructure and mechanical properties of 15Cr super martensitic stainless steel after different heat treatments were studied. The results show that the structures of the steel after quenching are lath martensite. With the raising of the quenching temperature, the original austenite grain size increases and the martensite platelet gradually coarsens. The microstructures of the tempered steel are tempered martensite and reversed austenite dispersed in the martensitic matrix.

The effects of martensitic transformation on the coaxing behavior were studied in austenitic stainless steels. The materials used were austenitic stainless steels, type 304 and 316. Conventional fatigue tests and stress-incremental fatigue tests were performed using specimens subjected to several tensile prestrains from 5% to 60%. Under conventional tests, the fatigue strengths of both steels increased with increasing prestrain. Under stress-incremental tests, 304 steel showed a marked coaxing effect, where the failure stress significantly increased irrespective of prestrain level. On the othe

The uniform microstructures consisting of elongated austenite and martensite nanocrystallites evolved at large total strains, resulting in tensile strength above 2000 MPa in the both steels.

Thermochemically produced stainless steels with varying nitrogen content were slid dry on high carbon martensitic steel counterfaces using a pin bush machine. The running-in wear was high but the steady state wear decreased with increased nitrogen contents of the steels. A work hardened layer formed on the pins, the degree of hardening increasing with the nitrogen content of the steels. The hard pins caused a considerable amount of wear of the bushes, possibly, by ploughing. The pins wore by transfer and oxidation and, by interfacial shear and, probably, brittle fracture of the work hardened l

Austenitic stainless steel, or the so-called transformation-induced plasticity steel, exhibits high nonlinearity when strain-induced martensitic transformation occurs at various strain rates and temperatures, especially at cryogenic temperatures and high strain rates. The strong hardening, which is caused by the strain-induced martensitic transformation, is an important property of austenitic stainless steel. In this work, a viscoplastic model that considers the martensitic phase transformation of austenitic stainless steel is introduced in order to identify nonlinear mechanics, including the

Hydrogen-charging up to 100 hours weakly influences stages of plastic flow, strength properties and elongation of the UFG steels.
