WebMay 6, 2011 · Sinus tachycardia is the term used to describe a faster-than-normal heartbeat — a rate of more than 100 beats per minute versus the typical normal of 60 to 70 beats per minute. Well over 99 percent of the time, sinus tachycardia is perfectly normal. The increased heart rate doesn't harm the heart and doesn't require medical treatment. WebFeb 1, 2024 · Here, plasticity is governed by deformation twinning, in which kinetics is tightly correlated with the loading rate. Over the investigated range of strain rates, a hardening-like effect is found to shift the onset of the structural bcc-to-hcp phase transformation to a high, almost constant stress during the ramp compression regime.
