In the utility model, be provided with thermopair in the described thermometer hole.
In the utility model, described test rod is made of overcoat, plug, described overcoat one end end face has the staged inner concave of a degree of depth at 2～15mm, the other end is provided with positioning screw hole, described plug is inserted in the described overcoat, and an end face overlaps with the staged inner concave that described overcoat end face is provided with.
In the utility model, described plug cross section is that the diameter 3～10mm circle or the length of side are the foursquare tested aluminium alloy of 3～10mm.
The utility model has following advantage owing to adopt the said structure form:
1, adopts circular or foursquare coupon, be convenient to mechanical workout;
2, specimen size is little, can reduce and make the required measured material of test rod, helps reducing the cost of test full hardening deepness;
3, at the coupon rod thermometer hole is set on one's body, when realizing that full hardening deepness is measured, the cooling temperature of specified point curve (cooling curve) over time on the energy measurement test rod again is the quenching sensitive of the research aluminum alloy materials condition of providing convenience.
4, the staged inner concave is set and prevents effectively that ejection medium from splashing to that the type of cooling to test rod impacts on the cylinder of test rod.
5, adopt the structure of plug-in mounting plug in the overcoat, further reduce the cost of manufacture of coupon, simultaneously,, thereby make experimentation cost lower because the overcoat of test rod can use repeatedly.
In sum, the utility model is simple and reasonable, processing and manufacturing is easy, cost is low, specified point process of cooling real time temperature on the measurement test rod can be provided, when implementing depth of hardening research, can obtain aluminum alloy materials quenching sensitive data, be applicable to the test sample of the quench cooled technology of heat-treatable strengthened aluminum alloy material hardening capacity, aluminium alloy quenching sensitive and research and development high-hardenability novel aluminum alloy and big gauge material and member.
