Find the time it is expected to take the specimen to elongate 1% of its initial length (200 mm) working at 650°C℃ under 200 kN of constant force using the graph provided below. Assume a single mechanism operates. The cross section of the specimen is 600 mm².

You need to find the activation energy and the stress exponent) Find the time it is expected to take the specimen to elongate 1% of its initial length (200 mm) working at 650°C℃ under 200 kN of constant force using the graph provided below.
