The film boiling state of a refrigerant is maintained for a time longer than in the prior art by t to lower the nuclear boiling start temperature to a temperature at which the material proof strength of a work exceeds thermal stress, thereby lowering the cooling rate of the work. In addition, by controlling the cooling rate in hardening, the film boiling state of the refrigerant is maintained to a temperature at which the material proof strength exceeds thermal stress, thereby cooling the work at a temperature equal to or higher than the critical cooling rate of the work.

Light-alloy casting heat treatment method

A metallic porous product is produced by applying a slurry of a mixture of skeleton constituent metal particles and property modifying particles to an inflammable porous foam, burning the inflammable porous foam having open pores by heat to provide a metallic skeleton structure, and sintering the metallic skeleton structure.

Metallic porous product and composite product thereof and method of

A hydrogen gas supply system for a hydrogen engine has a hydrogen gas cartridge which is detachably attached to the engine. The cartridge has a casing in which hydrogen gas storage alloy and a heating medium passage for heating the hydrogen gas storage alloy are housed. The engine is provided with a hydrogen gas supply passage which leads hydrogen gas discharged from the hydrogen gas cartridge to the engine, a heating medium supply passage which supplies heating medium to the heating medium passage in the hydrogen gas cartridge and a heating medium return passage through which the heating medium flows out of the hydrogen gas cartridge is returned. The hydrogen gas cartridge is provided with a hydrogen gas takeout port, a heating medium inlet and a heating medium outlet. The hydrogen gas takeout port, the heating medium inlet and the heating medium outlet are respectively connected to and disconnected from the hydrogen gas supply passage, the heating medium supply passage and the heating medium return passage in response to attachment and detachment of the hydrogen gas cartridge.
