Zirconium Hafnium Carbon Properties
Why should we use Hafnium zirconium carbon(ZHM alloy) ?
Hafnium Zirconium Carbon Properties:
Hafnium zirconium carbon(ZHM alloy) advantages compared to other molybdenum alloy:
Above 40%~50% tensile strength higher than TZM alloy
Better creep resistance
Higher recrystallization temperature
Better welding properties.
Multicomponent Hafnium Zirconium Carbon(ZHM alloy) Systems:
| Alloy Series | Grades | Nominal Composition | Recrystallization Temperature(℃) |
| Mo-Hf-Zr-C | |||
| ZHM | Mo-0.5Zr-1.5Hf-0.2C | ~1500 | |
| ZHM4 | Mo-1.2Hf-0.4Zr-0.15C* | ~1500 | |
| ZHM6 | Mo-1.5Hf-0.5Zr-0.19C* | ~1500 | |
| ZHM7 | Mo-1.8Hf-0.6Zr-0.23C* | ~1500 | |
| ZHM8 | Mo-2.1Hf-0.7Zr-0.27C* | ~1500 | |

ZHM alloy's room-temperature tensile strength is higher than TZM molybdenum alloy of approximately 40% to 50% and it t is the highest intensity molybdenum alloy.
ZHM alloy is still in the development stage, mainly processed into ingots was built, as superalloy powder isothermal forging die. ZHM alloy will be another super alloy in the future.
