Jan 01, 2018 · Constructional high-temperature ceramics based on ZrB 2, which is capable of long-term operation in an oxidizing environment at temperatures above 1500 °C, has low density and high strength characteristics at elevated temperatures. The use of such materials is promising in engineering industry, as well as for protective coatings deposition. CN102400030A - Method for adding nitrogen element into The method is simple and reliable; and after furnace charges are molten completely, refined and deoxidized, and the nitrogen-containing iron alloy is added under the protective atmosphere of the argon and is deoxidized finally, the molten steel is tapped and poured, so the aim of adding the nitrogen element accurately at low cost is fulfilled, the content of the nitrogen element can be controlled

Effect of nitrocarburizing and post-oxidation on fatigue

Researchers have found that the initiation points of VHCF cracks in high strength steel [16,17], aluminum alloy [18,19] and cast iron [20,21] Page 1 of 14 AUTHOR SUBMITTED MANUSCRIPT Experimental Research on Parameter Optimization for High Nov 01, 2017 · 42CrMo is a typical ultrahigh strength steel which is widely used as crankshaft and connecting rod of engine. In this paper, the influence of cutting parameters on cutting force and surface quality during dry turning process of ultrahigh strength steel 42CrMo was investigated. Journal of Iron and Steel Research International New bainite kinetics of high strength low alloy steel in fast cooling process: Dynamic mechanical behavior of ultra-high strength steel 30CrMnSiNi2 A at high strain rates and elevated temperatures: Effects of Processing Variables on Microstructure and Yield Ratio of High Strength Constructional Steels:

Prediction and analysis of EDM die sinking machining of PH 15-5 stainless steel Missouri University of Science and Technology Scholars' The initial dissolved aluminum in the steel ranged from 14ppm to 503ppm. The steel composition is similar to that of 42CrMo steel. The example composition of the steel is shown in Table 1. CaO-SiO. 2-Al. 2. O. 3. slags were used, which were the mixtures of ultra pure powders of CaO (48%), SiO. 2 (6%) and Al. 2. O. 3. (46%). The original slag basicity CaO/SiO. 2 =8. Optimization the working parameters of as-forged 42CrMo Jul 01, 2020 · 42CrMo steel belongs to low-alloy medium carbon steel and also belongs to ultra-high-strength steel. In this study, thermal compression tests (800°C - 1200°C, 0.01s-1 - 10s-1) and subsequent calculations proved that many material constants of 42CrMo alloy steel have a similar functional relationship with Z parameter:Material constants = a*Z b.

Ultrahigh - definition of ultrahigh by The Free Dictionary

Ultrahigh strength steel is a new kind of structural materials [1] developed from constructional alloy steels, which with the tensile strength over 1500 MPa or yield strength over 0 MPa. Experimental Research on Parameter Optimization for High Efficiency Hard Turning of Ultrahigh Strength Steel 42CrMo Ultrahigh-Strength Steels Properties and Selection This article describes the commercial structural steels capable of a minimum yield strength of 0 MPa (200 ksi). The ultrahigh-strength class of constructional steels includes several distinctly different families of steels. The article focuses on medium-carbon low-alloy steels, medium-alloy air-hardening steels, and high fracture toughness [DOC]University of Cambridge · Web viewThese authors investigated very high temperature deformation of 42CrMo steel at strain rates up to 50 s-1. The modifications introduced were applied to a 2124-T851 aluminum alloy [94]. The effect of temperature and strain rate behaviour can be represented by a Zener-Hollomon parameter in an exponent-type equation.
