Effect of Ca concentration on Microstructure formation behaviors in AZ61 magnesium alloy

the effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...

Microstructure-sensitive investigation of magnesium alloy fatigue

Effect of Stress Ratio on Fatigue Crack Growth Behavior of Magnesium Alloy AZ61 under 3.5 Mass% NaCl Spray Environment*

Fatigue crack growth behavior of AZ61 magnesium alloy was investigated in low humidity (55% relative humidity) and 3.5% NaCl spray environments under various stress ratios. Fatigue crack growth rates became higher with increasing load ratio for both environments. However, the results of fatigue crack growth test under 3.5% NaCl spray environment showed lower fatigue crack propagation rate compa...

Ductility Improvement of an AZ61 Magnesium Alloy through Two-Pass Submerged Friction Stir Processing

Friction stir processing (FSP) has been considered as a novel technique to refine the grain size and homogenize the microstructure of metallic materials. In this study, two-pass FSP was conducted under water to enhance the cooling rate during processing, and an AZ61 magnesium alloy with fine-grained and homogeneous microstructure was prepared through this method. Compared to the as-cast materia...

the effect of hot deformation on the microstructure of az91 magnesium alloy

due to the great variety of applications of magnesium alloys with superior mechanical properties, recent studies have been focused on the hot deformation behavior and microstructure of magnesium alloy castings. although there have been several recent investigations on the microstructure of wrought magnesium alloys after hot deformation, a limited number of studies have been conducted with regar...
