摘要： A heat treatment method of steel is capable of enhancing wear resistance, mechanical properties and dimensional stability of the steel due to the reduction of the retained austenite amount to substantially zero. In the method, an article of the steel is subjected to a quenching and then subzero treatment including cooling it at a cooling rate of 1 to 10° C./min. to a cooling temperature and holding the cooling temperature for a predetermined period of time.

摘要： A golf club head is comprised of cryogenically treated steel resulting in the striking face having a reduced face thickness of between 0.115 inches and 0.130 inches, and therefore, a reduced striking face mass. Extra material which is eliminated from the striking face, is distributed in other areas of the club head to enhance performance. In an iron club head embodiment, the club head includes a heel portion, toe portion, bottom sole portion, top ridge portion, hosel portion, striking face, rear surface, and peripheral mass on the rear surface which forms a rear cavity. A cantilevered mass extends from the bottom sole portion toward the top ridge portion within the rear cavity, spaced apart from the rear surface. In a wood club head embodiment, the club head includes a hollow body having an inner cavity delimited by a sole portion, a striking face, a heel portion, a toe portion, and a crown portion which links the striking face, toe portion, and heel portion. A weight chip of higher density material is located along the sole portion of the head. The iron and wood embodiments enjoy an optimum weight distribution which is below and behind the sweet spot, producing higher trajectory golf shots and more forgiving off-center hits.

摘要： A clutch disc spring for a land vehicle, such as an over-the-road truck or an automobile, which has an increased life. The spring, formed of ferrous material, is cooled by vaporizing low temperature nitrogen to slowly, cryogenically cool the spring to a temperature of about −300 degrees Fahrenheit and maintain the spring at that temperature for several hours. The cryogenic treatment converts retained austenite within the spring to martensite, thereby improving the mechanical properties of the spring. The spring is then tempered to temper the newly formed martensite, further improving the mechanical properties of the spring. These improved mechanical properties include better wear resistance, strength and resistance to fatigue.

摘要： A metallurgical process expands the grain structure in a heat sink from a fine grain to a coarse grain to improve the thermal conductivity of the heat sink. The temperature of the heat sink is raised to a level high enough to lead to a secondary re-crystallization grain growth in the metal alloy. The temperature of the heat sink is then gradually lowered to a cryogenic temperature and then immediately brought back up to ambient temperature to strengthen the material.

摘要： A method of heat treating 9Ni-4Co-0.30C class steel alloy uses shortened treatment time for normalizing, austenitizing, and tempering, as well as a lower tempering temperature, when compared to conventional heat treatment for this class of alloy material. The improved process is especially beneficial for large section parts, resulting in increases in yield and ultimate strength, combined with substantial increases in impact toughness.
