... and 1100°C for 10, 30 and 100 minutes. It was believed that the H-4 and M-11 locations experienced only low temperatures. These control specimens were polished, etched and compared to the TMI-2 boat specimens. Specimens were cut from the boat specimens and studied by the VIP members. In the USA...
