Abstract
Изобретение относитс к испытани м материалов, а именно к способам измерени твердости. Целью изобретени вл етс расширение номенклатуры испытуемых материалов при измерении динамической твердости. Поставленна цель достигаетс тем, что в способе, заключающемс в воздействии нагрузки N через индентор на образец, мгновенно снимают нагрузку, измер ют деформацию д, обусловленную обратным упругим последствием, а твердость определ ют по формуле HI -,-, где N - нагрузка; дУ - деформаци обратного упругого последстви . 1 ил.The invention relates to the testing of materials, and specifically to methods for measuring hardness. The aim of the invention is to expand the range of test materials when measuring dynamic hardness. The goal is achieved by the fact that in the method consisting in applying the load N through the indenter to the sample, the load is instantaneously removed, the deformation e due to the reverse elastic consequence is measured, and the hardness is determined by the formula HI -, -, where N is the load; dU - deformation of the reverse elastic consequence. 1 il.

На чертеже изображена схема устрой- ;Ства дл релизации способа.The drawing shows a diagram of the device; STV for the implementation of the method.
Устройство состоит из индентора 1, измерител 2 деформации хрупкого элемента 3, например, охлажденной капли стекла с заостренным концом (батавска слезка).The device consists of an indenter 1, a gauge 2 of the deformation of a fragile element 3, for example, a cooled drop of glass with a pointed end (Batavian tears).
Способ реализуют следующим образом.The method is implemented as follows.
Подвод т индентор 1 к испытуемой детали 4 и прикладывают к нему нагрузку N, воздейству на поверхность детали 4 через хрупкий элемент 3. Величина нагрузки выбираетс такой, чтобы в детали возникли только хрупкие деформации. Отламывают заостренный конец хрупкого элемента 3, при этом капл мгновенно разрушаетс . Измеритель 2 деформации подвод т в точку А и замер ют деформацию обратного упруThe indenter 1 is applied to the test part 4 and a load N is applied to it, affecting the surface of the part 4 through the fragile element 3. The load value is chosen such that only fragile deformations occur in the part. The pointy end of the fragile element 3 is broken off, and the droplet is instantly destroyed. The deformation meter 2 is brought to point A and the deformation of the reverse elastic is measured.
