در این تحقیق تغییرات ریزساختار ناشی از کرنش در فولاد زنگنزن آستنیتی aisi304 با استفاده از روشهای غیرمخرب بارکهازن و جریانگردابی بررسی شده است. برای این- منظور نمونههای کششی در مقادیر مختلف کرنش کشیده شدند. مقادیر مارتنزیت با استفاده از آنالیز تصاویر متالوگرافی و روش xrd تعیین شدند. تصاویر متالوگرافی و نتایج xrd با افزایش کرنش افزایش مقدار مارتنزیت را نشان میدهند. خروجیهای ولتاژ نرماله، هارم...

Nowadays, Ni-free austenitic stainless steels are being developed rapidly and high price of nickel is one of the most important motivations for this development. At present research a new FeCrMn steel was designed and produced based on Fe-Cr-Mn-C system. Comparative studies on microstructure and high temperature mechanical properties of  new steel and AISI 316 steel were done. The results ...

Brangus steers (n=247) finished on pasture were used to evaluate the effects of post-mortem ageing and polymorphism CAPN1 316 and CAPN1 4751 markers on meat tenderness and objective colour measurements (CIEL*a*b*) of m. Longissimus dorsi. Ageing meat for 7 days decreased shear force (SF) by 13.7% and improved a* (8.4%) and b* (10%) compared to ageing for 1 day. No difference between 7 and 14 da...
