77 K and 873 K to study the effect of temperature on mechanical properties and deformation mecha- nisms. Ductility, yield and ultimate tensile strengths incr eased with decreasing temperature. EFFECT OF HEAT TREATMENT ON MECHANICAL After air cooling to 50-60°C, samples were immediately tempered 2 hr at different tempering temperatures (425°C, 500°C, 550°C, and 600°C). Another set of samples underwent double tempering:hardening to 1010°C (soaking for half hour); oil quenching to about 50-60°C; immediate tempering (2 hr + 2 hr) at 500°C, 550°C, 575°C, and 600°C.

Effect of Minimum Temperature on the Mechanical

Nov 01, 2018 · The effect of minimum temperature on the mechanical properties and reversed austenite content of 9%Ni steel subjected to cryogenic treatment was experimentally investigated. Cryogenic treatment with different temperatures and soaking time were conducted by combining with the newly developed quenching, lamellarizing and tempering (QLT) heat Effect of Sintering Temperature on the Interfacial and Apr 08, 2021 · In the present work, SiC fiber reinforced mullite matrix composites (SiCf/Mu composite) were prepared through a sol-gel process. The effect of sintering temperature on the interfacial and mechanical properties of the SiCf/Mu composite was studied comprehensively and deeply. The experimental results indicated that the micro-mechanical properties of mullite matrix and fiber/matrix

Effect of a Temperature on the Mechanical Characteristics

Aug 18, 2020 · As temperature increases within the specified range, the relative elongation at break monotonously decreases more than twice (2.91.3%). The elastic modulus changes insignificantly within a temperature range of (40)20°C; when the temperature rises to 150°C, it Effect of temperature on mechanical properties of ultra Apr 30, 2021 · Being a relatively new construction material, there is a lack of temperaturedependent mechanical property data on ultrahigh performance concrete (UHPC). To address this knowledge gap, this paper presents results from an experimental study on the effect of temperature on mechanical properties of UHPC.

jection temperatures may lead to burns and severe weakening of the structure. The temperature range of 180 C is chosen based onC220 the appropriate temperature range of injecting pure polystyrene. The effect of increasing the waste ratio in the blend on four responses is investigated as well. Consequently, both temperature and waste ratios International Journal of Engineering Trends and time and temperature can give the desired mechanical properties during tempering, but, in general, temperature will have the highest impact on tempering effect [14]. Previous studies [15-17] have shown that with increasing the tempered temperature, the martensite transforms to the ferrite and carbides.

Investigation of the Effects of Mold Temperature, Test

Aug 05, 2019 · This paper investigates the time and temperature dependence of a ductile polymer, polypropylene, from the mechanical point of view. As the polymeric specimens have been manufactured by the injection molding process, the influence of mold temperature has been also subjected to the study. Compression tests have been performed both in quasi static and dynamic range (10 3 /10 3 s Nanoindentation Investigation of Temperature Effects on modulus of Naon® 117 membranes were tested at temperatures between 10 and 70 C, and the effects of indentation depth and applied temperature on the mechanical response of the membrane was investigated. 2.
