  1. I have the following comments:
    1) Bodycote heat treatment curves and report should be in English language.
    2) Which function has the company Mecaero; written on the Bodycote report?
    3) the Heat treatment curves (45min at 829°C) and (2h at 490°C )
    curve at 829°C shows app. 3h
    Curve at 429°C shows also app. 3h.
    Please confirm that the tolerances (45min, + 45min and the longer temperature holding time for both temperatures do not have any influence on the material properties.
    4)The report called:
    Heat treatment performed Thermi-Garonne following the internal specification TT0164 and in accordance to AMS2759-1. Please confirm that the heat treatment was performed to AMS 2759-1 and that the reference document referenced on the heat treatment report TTG 000 defines the same requirements than the in the report referenced AMS.
    On Bodycote certificate, time for the heat treatment curves at 829°C corresponds to furnace holding time and not metallurgical time.
