Uniaxial creep-to-rupture tests at 550 and 600 °C under a constant load of 300 MPa have been performed to study the effect of lead-bismuth eutectic (LBE) on the creep failure behavior of a solution-annealed 15-15Ti steel. The results show that the s

The objective of this work is to evaluate creep behavior of a maraging steel (300 grade) solution annealed before and after superficial treatment of plasma nitriding. Creep tests were conducted on a standard creep machine at stress range of 200 to 50

Creep behavior and deformation substructures of Mg–Y binary alloys containing 0.2–2.4 mol% Y have been investigated at 550 K under 50–200 MPa. Creep strength is remarkably improved by a small addition of yttrium as compared with aluminum and ma

Samples of fine-grained (approximately 9 μm) and coarse-grained (approximately 45 μm) hematite ores with almost random crystallographic preferred orientation (CPO) were deformed in high pressure, high temperature (400 MPa, 850-1 000 °C) torsion ex

The thermal conductivity of compacted graphite cast iron (CGI) after creep test (temperature ranging from 350 °C to 550 °C; stress ranging from 40 to 150 MPa) was measured at different testing temperatures (200 °C to 550 °C) in an argon atmospher

Heat-to-heat variation of creep strength is significant in grade 91 (Gr.91) steel, but the causes of the variation have not been well understood yet. In the present paper, creep rupture data of 14 heats of Gr.91 steel were analyzed paying attention t
