Цель изобретени - повышение прочности , относительного удлинени ударной в зкости при температурах до -60°С, процента волокна в изломе, удельной энергоемкости волокна, коэффициента изотропности.The purpose of the invention is to increase the strength, the relative lengthening of toughness at temperatures down to -60 ° C, the percentage of fiber in the fracture, the specific energy content of the fiber, the isotropy coefficient.
Стали выплавл ли в 50-килограммовой индукционной печи. Стали разливали на 17- килограммовые слитки, ковали на сутунки и прокатывали на лист толщиной 12 мм. ВThe steel was smelted in a 50 kg induction furnace. Steel poured into 17-kilogram ingots, forged on billet and rolled on a sheet with a thickness of 12 mm. AT
табл. 1 дан химический состав сталей, а в табл. 2 - полученные механические свойства . Определены свойства при раст жении на образцах КР-1. Определена ударна в. з- кость образцов с м гким и острым надрезами КСИ и КСУ, а также образцов с трещиной. Оценена дол в зкой составл ющей в изломе ДВТТ, а также подсчитана удельна энергоемкость волокна Эу, определена анизотропи свойств по ударной в зкости по отношению величин ударной в зкости образцов с м гким надрезом на продольных и поперечных образцах.tab. 1 is given the chemical composition of steel, and table. 2 - mechanical properties obtained. Tensioning properties on KR-1 samples were determined. Defined in shock. softness of specimens with soft and sharp cuts of XI and XU, as well as specimens with cracks. The durability component in the FBTT fracture was evaluated, and the specific energy intensity of the Eu fiber was calculated, the anisotropy of the properties was determined from the impact strength in relation to the values of impact strength of samples with a soft notch on longitudinal and transverse samples.
