In order to increase the penetration ability of tungsten fiber-reinforced Zr-based bulk metallic glasses matrix composite rod. two multi-diameter tungsten fiber-reinforced Zr-based bulk metallic glasses matrix composites (MD-WF/Zr-MG) are designed. In MD-WF/Zr-MG-I. the diameters of tungsten fiber (WF) increase gradually from the inside to outside. https://hollandscountryclothinges.shop/product-category/horse-turnout-rugs/
