According to the results, at higher strain (0.1 s-1), strength is higher than that in low temperatures. It can be said that at higher strain rates the material does not
WebbSingle crystal Nickel-based superalloys exhibit an anomalous yield point, the yield stress increasing with temperature to a maximum at around 750 ºC. Here, we demonstrate in the alloy CMSX-4 at 750 ºC that, although there is virtually no effect of strain rate on the initial yield point, at slow strain rates a second mechanism can initiate leading to a …
