this experimental study investigated the effects of quenching and tempering heat treatment on fatiguebehavior and also tempering temperature and time holding of aisi 1060 steel. at first, the specimenswere austenitized at 800˚c for 1 hour, and then were quenched in the water bath of 25˚c temperature.after that, tempering process was done at the temperature of 250˚c, 450˚c and 650˚c for 1 and 2 ...

Powder-actuated (also referred to as low velocity or powder-driven) fasteners are commonly used to attach cold-formed steel framing members, usually a track, to a concrete or structural steel support. Although commonly used, their behavior is less well understood than other fasteners such as screws, bolts and welds. The AISI Cold-Formed Steel Design Manual does not explicitly address powder act...

The experimental investigations of the tool wear in turning of EN 31 alloy steel at different cutting parameters are reported in this paper. Mathematical model has been developed for flank wear using response surface methodology. This mathematical model correlates independent cutting parameters viz. cutting speed, feed rate and depth of cut with dependent parameters of flank wear. This model is...

The present work studies three variables (cutting velocity, feed rate, and cut depth) on hard turning cutting temperature of uncoated multilayer-coated carbide (TiN, TiN/TiCN, TiN /Al2O3/ TiCN) inserts are used in AISI 1045 alloy steel. tool's was measured simultaneously, measuring the tool-chip interface using infrared radiation (IR) pyrometer this investigation. This study investigated perfor...

Implantation using stainless steels (SS) is an example where an understanding of protein-induced metal release from SS is important when assessing potential toxicological risks. Here, the protein-induced metal release was investigated for austenitic (AISI 304, 310, and 316L), ferritic (AISI 430), and duplex (AISI 2205) grades in a phosphate buffered saline (PBS, pH 7.4) solution containing eith...

This paper presents the results of time and temperature resolved analysis of changes in phase composition and stresses/residual stresses during quenching and martensitic transformation of steel. Sample temperatures up to 900°C were reached with a specially-designed furnace, in which fast cooling of sample is executed by gas quenching. Stress development during quenching followed the expected tr...
