摘要： The invention relates to a method for estimating heat transfer during water quench of an aluminum part. The method includes: estimating the heat transfer of the aluminum part when a temperature of the part is greater than 500° C. using q=α(ΔT) (1); estimating the heat transfer of the aluminum part when the temperature of the part is greater than T2 and less than 500° C. using q=k1ΔTk2 (4); estimating the heat transfer of the aluminum part when the temperature of the part is greater than T1 and less than T2 using a critical point function equation selected from: q = q max - q 0 ⁡ ( T metal - T max T 2 - T 1 ) 2 , ( 3 ) q n = a 0 + a 1 ⁢ Δ ⁢ ⁢ T + a 2 ⁢ Δ ⁢ ⁢ T 2 + a 3 ⁢ Δ ⁢ ⁢ T 3 + … + a n ⁢ Δ ⁢ ⁢ T n , ( 6 ) q = q max - ( 1 - 4 ⁢ ( ( 1 - φ ) ⁢ ( T metal - T max T 2 - T 1 ) 2 ) , ( 7 ) q = q max - ( 1 - ( T metal - T max T 2 - T 1 ) 2 ) , ⁢ or ( 8 ) q ⁡ ( T 1 ) = q ⁡ ( T 2 ) = φ ⁢ ⁢ q max ; ( 9 ) estimating the heat transfer of the aluminum part when the temperature of the part is less than T1 using q=c1ΔTc2 (5). Systems, methods, and articles to predict transient heat transfer, or temperature distribution, or both of a quenched aluminum casting are also described.
