Deformation behaviour of aluminium low-micron MMCs and MMNCs at warm working temperatures (0.3-0.5 Tm)

Mechanical Behaviour of Commercial Aluminium Wrought Alloys at Low Temperatures

THE DEFORMATION BEHAVIOR OF AZ31 MAGNESIUM ALLOY AT ELEVATED TEMPERATURES

AZ31 magnesium alloy is considered as a promising alloy in various applications and industries. Furthermore, to design a proper hot working process (rolling, forging and extrusion), the assessment of hot working behaviour of the alloy is necessary. Accordingly, the hot deformation behaviour of AZ31 alloy was studied through hot compression testing method This was carried out in a wide range of ...

Effects of zeolite on growth and hematology of rainbow trout (Oncorhynchus mykiss) kept at low temperatures

It is known that zeolite, tested in animal feeds in recent years, has a positive effect on fish growth and many physiological parameters. For this purpose, rainbow trout (Oncorhynchus mykiss) was fed with feeds containing zeolite at different rates (1%, 3%, and 5%) for three months in the present study. Fish growth parameters (live weight gain, specific growth rate, feed conversion rate, condit...

Application of a Composite Model in the Analysis of Creep Deformation at Low and Intermediate Temperatures

The creep behaviors of TA2 and R60702 at low and intermediate temperature were presented and discussed in this paper. Experimental results indicated that an apparent threshold stress exhibited in the creep deformation of R60702. Meanwhile, the primary creep phase was found as the main pattern in the room temperature creep behavior of TA2. Compared with exponential law, the power law has been pr...

PREDICTION OF HOT DEFORMATION BEHAVIOUR OF A PH STAINLESS STEEL AT HIGH STRAIN RATES

In this study the hot deformation behaviour of a precipitation hardened (PH) stainless steel at high strain rates has been predicted through hot compression testing. Stress-strain curves were obtained for a range of strain rates from 10-3 to 10+1 S-1 and temperatures from 850 to 1150°C. Results obtained by microstructure and stress-strain curves show that at low temperatures and high strain rat...
