Description
соединени , имеют высокую температуру плавлени и не мен ют свою форму и свойства при введении сплава в жидкую сталь. Поэтому при затвердевании стали они служат готовыми центрами кристаллизации. Увеличение их количества значительно измельчает величину карбидного зерна стали, уменьшает степень дендритной ликвации, что повышает выход годного при гор чей деформации.compounds have a high melting point and do not change their shape and properties when an alloy is introduced into molten steel. Therefore, during the hardening of steel, they serve as ready crystallization centers. An increase in their number significantly crushes the value of carbide grain of steel, reduces the degree of dendritic segregation, which increases the yield of the product during hot deformation.
Пример. Предлагаемый сплав получают в услови х ферросплавного проиэводства на основе технологического процесса выплавки ферросиликокальци . Концентрат циркони присаживают в шихту, металлический магний и алюминий - в ковш при выпуске сплава из печи. Азотирование сплава провод т в вакуум-камере, в которой после создани вакуума создают повышенное давление азота. Получают сплавы различного состава. Из твердого сплава готов т шли- фы, которые исследуют под микроскопом при увеличении ЮО.Example. The proposed alloy is produced under the conditions of ferroalloy production on the basis of the process of smelting ferro silicocalcium. The zirconium concentrate is placed in the mixture, the metallic magnesium and aluminum in the ladle with the release of the alloy from the furnace. The nitriding of the alloy is carried out in a vacuum chamber, in which, after a vacuum has been created, an increased nitrogen pressure is created. Get alloys of different composition. Grinding grains are prepared from the hard alloy, which are examined under a microscope with increasing SO.
