Effect of silicide coatings on the mechanical properties of alloy 5VMTs

The paper examines the effect of silicide coatings and testing media on the strength and plasticity of alloy 5VMTs between 25 and 1100°C. It is established that uncoated samples tested in argon have higher strength and plasticity over the entire temperature range of interest than coated samples tested in argon and air. The major cause of decrease in the mechanical properties of coated samples is the silicide layer whose properties depend on testing temperature.
