  We use ASCA data to obtain two-dimensional maps of the gas temperature in
three clusters: A754, A3558 and Triangulum Australis (the maps of A2256, A2319,
A2163 and A665, also presented at the conference, have since appeared in [5]).
All clusters from our sample show considerable temperature decline with radius
at r ~ 0.5-1 h^{-1} Mpc, most prominently in distant A2163 and A665. The three
clusters presented here also feature asymmetric spatial temperature variations,
which may be naturally attributed to the effects of a subcluster merger. As an
example, we show that the Triangulum Australis gas temperature and density maps
indicate recent nonadiabatic heating, presumably by merger shocks. Unlike most
of the clusters, the systems in our sample lack cooling flows (with the
possible exception of a weak one in A3558), thus we may be probing the younger
members of the cluster population.
