This study describes the results of studying the effect of modification/micro alloying with hafnium and alloying with tantalum on the morphology and distribution of the carbide phase in the ZhS3DK-VI alloy microstructure. The carbide phase is an integral structural component of the microstructure of nickel heat-resistant alloys. has a tremendous impact on the strength characteristics ... https://www.freeebookfinder.com/product-category/welding-helmet-accessory/
