Effect of Titanium Boron on Thixotropy of ZL104

In this paper, the effects of titanium and boron refinement treatment on microstructure changes during semi-solid remelting of ZL104 aluminum alloy were studied. The experimental results show that the elemental titanium and boron significantly refine the spherical primary α-Al grains of semi-solid ZL104 aluminum alloy, and the primary grains are fine and ideal spherical. Titanium and boron refining mechanism: Titanium and boron effectively refine the as-cast microstructure of ZL104 alloy, improve the conditions of primary grain spheroidization, and improve the roundness and uniformity of spherical grains.

Saliva Collection Kit

This product is used in collecting high-quality DNA/RNA samples from saliva and can be used in various biological experiments such as enzymatic hydrolysis, PCR, and next-generation sequencing. It is widely used for the collection and preservation of specimens in hospitals, scientific research institutions, and families. The collection process is easy and painless, and will not cause any damage or discomfort to the human body.
