(b) Both martensite and bainite form at a cooling rate of 1°C/s.
(c) Martensite, proeutectoid ferrite, and bainite form at a cooling rate of 0.1°C/s.
(d) Martensite, proeutectoid ferrite, pearlite, and bainite form at a cooling rate of 0.01°C/s.
What Is Room Temperature?
The temperature of a room as measured by a thermometer. The ideal temperature is one where people can comfortably wear everyday clothing. For the majority of people, it's either the temperature they set the thermostat to or the usual temperature of their home. Room temperature is frequently defined in science.
