Text Correction


In the original publication [1], there was an error in the sentence of “The as-extrusion rods were kept in muffle furnace at 400 °C for 2 h to complete solid solution of Al 7075; the billets and die were preheated at 430 °C and then immediately extruded at 320 °C with an extrusion ratio 25:1 and an extrusion speed of 0.3, 0.7, 1.2 and 2.1 mm/s, respectively.”


A correction has been made to the “2.1 Fabrication of Mg/Al Composite Rod”, “Paragraph 1”:


“The billets were preheated at 400 °C for 2 h and then immediately extruded at 320 °C with an extrusion ratio 25:1 and an extrusion speed of 0.3, 0.7, 1.2 and 2.1 mm/s, respectively.”


The authors would like to apologize for any inconvenience caused.
