Paper Title:
The Boron Effect on Mechanical Properties of Aged 2024 Aluminum Alloy
  Abstract

2024 Aluminum Alloy is widely used in aeronautical applications. The Alloy's strength is increased by Precipitation Hardening which is the aging and solution of strength and is widely used in T6 state. Bearing in mind the effect of Boron in shorting the aging time, the pure material of B2O3 was used in order to add Boron to 2024 Alloy, so Alloying was done. By testing mechanical properties and microstructure observations, good results were achieved in Boron effect on this alloy's quench in comparison with those alloys lacking Boron. The outcomes depicted that this element addition increases hardness and tensile strength in aging process. In a way that the hardness of the alloy after controlled quench in one hour natural aging was reached to 93HB from 73HB and to 134HB in one hour artificial aging in 110°C. Such difference in hardness amount is due to better distribution of precipitates.
