The desired outcome requires the completion of three steps: <a href=\"https:\/\/haertha.de\/en\/verfahren\/loesungsgluehen\/\" target=\"_self\">solution annealing<\/a>, quenching, followed by ageing (during which the actual precipitation takes place).<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"font-weight: 400;\">Solution annealing (diffusion annealing, homogenising)<\/span><\/h3>\n<p class=\" translation-block\">In order for the subsequent precipitation to succeed, <strong>all necessary elements must first be present as dissolved elements<\/strong>. <a href=\"https:\/\/haertha.de\/en\/verfahren\/loesungsgluehen\/\" target=\"_self\">Solution annealing<\/a> is used for this purpose. During this step, the correct temperature is of key importance. It must be high enough to minimise the presence of coarse particles. However, it must also not be too high, because otherwise structural components will melt, rendering further processing impossible.<br>\n<br><\/p>\n<p class=\" translation-block\">This process may only <strong>take a few minutes, but can also last several hours<\/strong>. This depends on the size of the component, the fineness or coarseness of the microstructure, the alloy type, and the processing of the semi-finished product (e.g. forged, pressed, etc.).<\/p>\n<p>&nbsp;<\/p>\n<p class=\" translation-block\"><span>INFO: Dispersoids<br>\nThe so-called dispersoids are precipitated as early as <a href=\"https:\/\/haertha.de\/en\/verfahren\/loesungsgluehen\/\" target=\"_self\">solution annealing<\/a>. These particles impede the movements of the grain boundary and thus control recrystallisation. Due to their size and low concentration in the material, they only cause a negligible increase in strength.<\/span><\/p>\n<p class=\" translation-block\">The next step in the process is quenching in a suitable medium. Suitable media are water or oil, and also gas or compressed air. The quenching medium depends on the material. <strong>Quenching prevents diffusion<\/strong>, and causes the mixed crystal to assume a metastable, oversaturated, and single-phase state.<\/p>\n<p>&nbsp;<\/p>\n<h3><span style=\"font-weight: 400;\">Ageing<\/span><\/h3>\n<p class=\" translation-block\"><strong>The actual precipitation\/ageing <\/strong>takes place in the final step of the process. The temperature determines the duration and the type of the precipitation. Factors such as nucleation and precipitate maturation can be adjusted.<br>\n<br><\/p>\n<p class=\" translation-block\">The correct <strong>temperature for precipitation <\/strong>depends primarily on the material alloy. For aluminium alloys and maraging steel, the temperatures range between 150 \u00b0C and 190 \u00b0C and between 450 \u00b0C and 500 \u00b0C respectively.<br>\n<br><\/p>\n<p class=\" translation-block\">While the diffusion or precipitation is accelerated by the temperature increase,<strong> the oversaturated, single-phase mixed crystal is transformed into a two-phase alloy<\/strong>.<br>\n<br><\/p>\n<p class=\" translation-block\">The<strong> first phase is the matrix <\/strong>\u2013 it is coherent in terms of volume, and usually makes up the larger portion.

Instead of polymorphic conversion, diffusion must be used to harden them.<\/p>\n<p>&nbsp;<\/p>\n<p class=\" translation-block\">For example, <strong>rivets made of duraluminium<\/strong> are subjected to age hardening. Besides aluminium, duraluminium contains 4% copper and 1% magnesium. It undergoes solution annealing at 495 \u00b0C to 505 \u00b0C. Quenching is followed by the ageing step in order to attain the final strength. This can take place by natural ageing at room temperature or by artificial ageing. Aluminium alloys treated by age hardening are considered susceptible to corrosion as the treatment does not allow the formation of an oxide layer. Freezing at -18 \u00b0C can be used as a means to delay age hardening, in order to achieve a longer processing time.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/p>\r\n                    <div
