      abstract     = {Dilute Mg alloys processed by the rapidly solidified ribbon
                      consolidation (RSRC) technique are candidate materials for
                      structural applications due to their enhanced mechanical
                      performance. The thermal stability of the structure in these
                      alloys strongly influences their mechanical performance at
                      elevated temperatures. In this study, an RSRC-processed
                      $Mg–1\%$ $Ca–0.5\%$ $Zn–0.1\%$ $Y–0.03\%$ Mn
                      $(at\%)$ alloy was heated at a constant rate up to 833 K,
                      and concurrently in situ X-ray diffraction (XRD)
                      measurements were performed using synchrotron radiation in
                      order to monitor the changes in the structure. In addition,
                      ex situ electron microscopy investigations were carried out
                      before and after annealing to complete the XRD study. On the
                      basis of XRD results, the stages of the microstructure
                      evolution during heating were identified. In addition, the
                      thermal expansion coefficients of the matrix and the Mg2Ca
                      secondary phase were determined. Between 299 and 400 K, the
                      lattice constants of both the matrix and the Mg2Ca phase
                      increased due to thermal expansion. In the temperature range
                      of 400-673 K, the increase of the lattice constants with
                      increasing the temperature continued, but their rate was
                      different for the two phases which can induce thermal
                      stresses. Between 673 and 753 K, the lattice constants of
                      the secondary phase did not change most probably due to the
                      compensating effects of the thermal expansion and the
                      decrease of the Ca content. In the temperature range of
                      753–793 K, the Mg2Ca phase started to dissolve. Between
                      793 and 833 K the dissolution continued, and additionally
                      the matrix was partially melted.},
