The ammonium metatungstate (APT) and tungsten powder prices are unchanged from the previous trading day on May 30, 2023 because most market participants are taking a watchful stance, waiting for the further instruction for the next month. 

The overall situation of China’s domestic rare earth market has gradually improved on May 31, 2023, which is mainly reflected in the rising price of light rare earths. The price of heavy rare earths is stable and relatively strong, and the price of NdFeB roughs is firm.

Molybdenum market quotation in China: sodium molybdate, ammonium molybdate and ammonium heptamolvbdate prices remain unchanged in the last trading day in May 2023.

At the beginning of the week, China tungsten price continued to be stable when the overall resource circulation in the tungsten market continued to be slow and most transactions were negotiated rationally. 

It was shown that the dispersion of K-bubbles could not directly affect the Charpy impact performance of the modified tungsten materials below 1000 °C, although the improvement of the impact performance by grain refinement induced by K-doping was significant. In the case of W-3% Re(H) and K-doped W-3% Re(H) plates, the effect of Re addition broadly consists of grain refinement effects caused by the inhibition of grain boundary movement by solute Re, and solid solution strengthening and softening effects caused by solute Re.

The ductile transfer temperature (DBTT) of modified tungsten materials can be evaluated by several test methods, such as tensile testing, bending testing, Charpy impact testing and fracture toughness testing. The DBTT is highly dependent on the test method, strain rate and specimen shape. Researchers have used Charpy impact and tensile tests to evaluate DBTT.

An increase in deformation ratio of modified tungsten materials can produce relatively rapid microstructural recovery and is generally less resistant to recrystallization. In the present study, materials with higher deformation ratios showed slightly lower recrystallization temperatures compared to materials with lower deformation ratios having the same major chemical composition.

China tungsten price continued to remain stable in the week ended on Friday, May 26, 2023 as most market participants tended to stabilize the market after the release of long-term contract prices from listed tungsten enterprises.
