Description
Известен способ исследовани прочностных свойств и трещиноустойчивости литых металлов и сплавов при высоких температурах, согласно которому образец, Образуюш,ийс при кристаллизации расплава в разъемной литейпой форме, состо щей из нижней и верхней полуформ, нагружают раст гивающим усилием , прилагаемым к верхней полуформе. При исследовании металла или сплава иеиосредственно в процессе его кристаллизации и дальпейщего охлаждени в литейной форме образец питаетс прибылью, расположеппой сверху и кристаллизующейс значительно позднее основной массы образца. В зтом случае весьма важно исключить механические воздействи на жидкий металл (сплав), сосредоточенный в прибыльной )части образца, так как любое смещение верхней полуформы измен ет услови кристаллизации металла.A known method for studying the strength properties and crack resistance of cast metals and alloys at high temperatures, according to which the sample, formed during the crystallization of the melt in a detachable casting mold, consisting of the lower and upper half-form, is loaded with tensile force applied to the upper half-form. In the study of a metal or alloy directly in the process of its crystallization and further cooling in the mold, the sample is fed by profit, located at the top and crystallizing much later than the bulk of the sample. In this case, it is very important to exclude mechanical effects on the liquid metal (alloy) concentrated in the profitable part of the sample, since any displacement of the upper half-form changes the conditions of crystallization of the metal.
Цель изобретени - повысить точность эксперимента.The purpose of the invention is to improve the accuracy of the experiment.
Дл этого раст гивающее усилие прилагают к нижней полу форме.For this, a tensile force is applied to the bottom floor of the mold.
Способ по сн етс чертежом.The method is explained in the drawing.
Нижн / и верхн 2 полуформы литейной формы 3 устанавливаютс соответственно на подвижной 4 и неподвил ной 5 траверсах разрывной испытательной мащины посредством сухарей 6, фиксаторов 7 и конусного кольца 8. Заливка расплава производитс через литейную воронку 9. После охлаждени металла (сплава) до необходимой температуры, контролируемой термопарой W подвижна траверса 4 перемещаетс вниз и посредствомThe bottom / and top 2 mold halves 3 are installed respectively on the movable 4 and the non-stem 5 crossheads of the rupture testing machine using crackers 6, clamps 7 and a tapered ring 8. The melt is poured through the casting funnel 9. After cooling the metal (alloy) to the required temperature controlled by the thermocouple W, the mobile yoke 4 is moved downwards and by means of
